I have used this app since the first version and after a month I upgraded to Worktime Pro. It has never failed me. Everything is organized and easy to access. The hours calculator is a lifesaver when it comes to making my monthly budget.
The only thing is that I wish you could input how much tax is taken off your wages so that the amount would be exact to what is on your pay cheque.
